To tbhom it may concern:

Be it known that I, Enwnv TAYLOR, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New Y'oik, have invented. certain new and useful Ijnprovements in the Preparation of Aluminous ompositions, of which the followin' is a specification.

,Myin'vention relates to the preparation of aluminous com ositions,-that is, compositrons. having 0 agf as the main ingredient constituting the asis of such composition, and in which oil is combined with the clay and vulcanized, and has for its object to facilitate the manufacture of such composition. v Ina separateapplication for Letters Patout "I have set forth an improved" composition in which ",clay'is thezbasis or main inient and in' whichthe clay is combined either naturallyor artificially with a certain proportion of sulfur and to which an oil is so added that it will become vulcanized by the sulfur, the said composition having main advantages resulting from its fluidity or:p asticity, accordingto the amount of oil employed, being serviceable as a waterproof coating or covering for many purposes and as an insulatin material.

While it is practicable to secure extremely suclradditioml have found that great advantage results from first. combinin the oil and the sulfur and partially vulcamzing the oil, thereafter adding it to the clay, and complating the vulcanization.

The clay may, if desired, be entirel free from s'ji'ilfur in its natural state, but have found that advantage results from employf ing suchclays as those known as blue clays,

foundonLong Island,,and elsewhere, where p there is j a; natural content of approximately two. andjon e-half per cent. of sulfur-results ring from the presence of metallic sulfids, such;.as sulfid ofniron in the-natural clay.

such aclay I combine "any desired proportion of vulcanized oil which I secure by adding sulfur-to the oil, heating the mixture to, ,about three hundred degrees'and for a su feient length of time'to partially vulthe oil. After such partial vulcanization-, ithe partially'vulcanized oil is added to we a this iient'may be obtained 101' Specification of Letters Patent.

the clay and the mixtureis then heated until the complete vulcanization of all the oil therein is effected. By this partial vulcan ization of the oil before mixing it with the clay, I'am able to so regulate the vulcaniza tion as to prevent any possibility of carbonization, and I have found that the partially vulcanized oil, when combined with the clay already having a'content of sulfur, results in securing a better vulcanizin efl'ect upon the entire mass, it bein very esirable'to com plete the vulcanization in the presence of the clay, as thereby I secure a more'suitable composition and efiective mixture of ingredients.

The above describedcomposition of mat-- ter'isserviceable forgvarious purposes, for coating and waterproofing difierent materials or articles, forming flooring, linings for tanks, or insulating covering for various artides and materials, and-can readily be hardened, or where suflicient oilis employed, can be applied as a; paint or formed into a plastic conditionrso asto be used lik'e iany putty or material.

. Without "limiting myself, to the propertions specified I fcl'aimas my invention;
